Vanadium Nitride Ua li cas

Peb txhua tus paub tias vanadium nitride yog cov khoom siv hlau zoo dua li cov hlau vanadium siab, siv vanadium nitride ua ib qho ntxiv, cov khoom siv nitrogen ntawm vanadium nitride tuaj yeem txhawb nqa nag lossis daus ntawm vanadium tom qab ua haujlwm kub, kom cov nag lossis daus me me, yog li ntawd. zoo dua txhim kho weldability thiab formability ntawm steel. Nws yog siv los ua cov khoom siv raw rau cemented carbide los tsim cov yeeb yaj kiab hnav-resistant thiab semiconductor. Nws yog ib qho tshiab thiab muaj txiaj ntsig vanadium alloy additive, uas tuaj yeem siv los tsim cov khoom siv high-strength low-alloy steel khoom xws li high-strength welded steel tuav, non-quenched thiab tempered steels, high-speed tool steels, thiab high-strength. cov yeeb nkab steel. Piv nrog ferrovanadium, vanadium nitrogen alloy tuaj yeem ntxiv dag zog thiab ua kom cov nplej zoo dua, txuag 30% ~ 50% ntawm vanadium piv nrog kev siv ferrovanadium, uas muaj txiaj ntsig zoo rau kev txhim kho cov hlau thiab txo tus nqi ntawm steelmaking. Nws kuj tseem tuaj yeem siv los ua cov khoom siv raw rau cemented carbide los tsim cov yeeb yaj kiab hnav-resistant thiab semiconductor. Yog li cas vanadium nitride tsim, cia kuv qhia koj

1. Vanadium nitride tuaj yeem npaj tau los ntawm kev sib xyaw stoichiometric carbon thiab vanadium pentoxide tag nrho thiab ua kom txo qis nitriding cov tshuaj tiv thaiv ntawm 1250 degree hauv qhov chaw chlorine. Nws tseem tuaj yeem npaj tau los ntawm reacting nitrogen-hydrogen tov nrog vanadium tetrachloride ntawm 1400 ~ 1600 degree; los yog npaj los ntawm reacting ammonia (NH3) nrog ammonium metavanadate (NH4VO3) ntawm 1000 ~ 1100 degree .

2. Txais txoj kev txo qis. Vanadium nitride tuaj yeem npaj los ntawm kev sib xyaw stoichiometric carbon thiab vanadium pentoxide tag nrho thiab ua kom txo qis nitriding cov tshuaj tiv thaiv ntawm 1250 degree hauv qhov chaw nitrogen. Nws kuj tseem tuaj yeem npaj los ntawm reacting nitrogen  hydrogen sib tov nrog vanadium tetrachloride ntawm 1400 ~ 1600 degree; los yog npaj los ntawm reacting ammonia (NH3) nrog ammonium metavanadate (NH4VO3) ntawm 1000 ~ 1100 degree .
